The Natural Resources and Environment Ministry will officially inform the Cabinet today of its plan to nominate Kaeng Krachan Forest Area as a candidate for Unesco World Heritage Site status.
A source said the proposal would be in line with the Operational Guidelines for the Implementation of the World Heritage Convention.
The Department of Natural Park, Wildlife and Plant Conservation has already compiled a report on the Kaeng Krachan Forest Area, which spans over 482,225 hectares on the eastern part of Tenasserim (Tanao Sri) mountain range.
The area covers the Mae Nam Pachi Wildlife Sanctuary, Kaeng Krachan National Park, Kui Buri National Park, the soon-to-be-established Chalerm Phrakiat Thai Prachan National Park as well as the zone linking Kaeng Krachan to Kui Buri National Park.
The Kaeng Krachan Forest Area is in the Indo-Makayan eco-region's Tenasserim-South Thailand semi-evergreen rainforest, where the Phetchaburi, Pachi, Pranburi and Kui Buri Rivers begin.
It is also home to more than 720 animal species including crested firebacks, red-billed malkoha, red-eyed bulbuls, banded langurs and fresh-water crocodiles.
According to the Department of Natural Park, Wildlife and Plant Conservation, the Kaeng Krachan Forest Area plays a crucial role in conservation. Its characteristics are similar to the Thungyai-Huai Kha Khaeng Wildlife Sanctuaries.
Spanning Kanchanaburi, Tak and Uthai Thani provinces, the Thungyai-Huai Kha Khaeng Wildlife Sanctuaries have had a World Heritage Site inscription since 1991.
